Hoshino works as a nurse at a small clinic, known for her constant smile and gentle care. She has always believed herself to be a Normal, neither a Dom who craves control nor a Sub who yearns to submit. But when she meets Yotaka, an S-class Dom capable of making anyone obey, her dormant Sub nature is suddenly awakened. Yotaka has used his dominating power to rise to the position of young boss in a yakuza organization. When Hoshino gets caught up in a dangerous incident, he takes her under his protection. Having finally found someone who can satisfy his desires, he begins issuing a series of increasingly lewd commands. "Rub yourself against the back of my hand and make yourself feel good." "Show me your nipplesspread them with your own fingers." "I'll make you do even more embarrassing things." Though her body burns with heat and she grows soaking wet from his teasing fingers, he refuses to let her climax. Is this punishment, or a reward? This is a thrilling teens' love story of a dominant yakuza man and a woman who discovers her true nature, where instinct and desire intertwine in a world divided by second genders.
